Embodiment

[0027] A production process of a 1-series aluminum alloy plate, comprising the following steps:

[0028] A. Melting and casting: Prepare aluminum alloy raw materials according to the following weight ratios: Si: 0.05%, Fe: 0.12%, Cu: 0.001%, Mn is 0, Mg: 0.004%, Zn: 0.002%, V: 0.008%, Ti : 0.004%, impurity 0.03%, Al: 99.81%, put the prepared aluminum alloy raw materials into the smelting furnace and mix them evenly, and then smelt them into liquid aluminum alloys. Ingot;

[0029] B. Homogenization: heat the aluminum alloy ingot obtained by melting and casting to 490°C and keep it warm for 13 hours to obtain a homogenized aluminum alloy ingot;

[0030] C. Extrusion: Send the homogenized aluminum alloy ingot into the extrusion cylinder of the extruder for extrusion to obtain aluminum alloy sheets. The extrusion machine is 1000T tonnage, and the temperature of the extrusion cylinder is 430±10°C. The extrusion ratio of the extrusion cylinder is 21.2, the extrusion speed is 6.0m / ...

Abstract

The invention belongs to the technical field of an aluminum alloy production process, and relates to a series 1 aluminum alloy plate production process. The production process comprises processes of smelting and casting, uniform annealing, extrusion, quenching, sawing and packaging, wherein the aluminum alloy raw material formula is prepared from 0.04 to 0.07 percent of Si, 0.10 to 0.15 percent ofFe, less than or equal to 0.03 percent of Cu, 0.001 to 0.03 percent of Mg, 0.001 to 0.03 percent of Zn, 0.001 to 0.03 percent of V, 0.003 to 0.04 percent of Ti, less than or equal to 0.05 percent ofsingle impurities, less than or equal to 0.15 percent of total impurities and the balance of Al; in the extrusion process, the whole mold work belt is ground to form a flow promoting angle being 2 to5 degrees; an extrusion mold is subjected to nitridation treatment before use, so that the surface hardness of the mold is maintained at 900 to 950HV; through the production process parameter optimized regulation and structure improvement on the extrusion mold, an series 1 aluminum alloy plate with the smooth and clean surface, surface roughness Rz being less than or equal to 10mu m and the electric conductivity reaching a value higher than 61 percent IACS or above is produced.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy production technology, and relates to a production technology of a 1-series aluminum alloy plate, in particular to a process capable of improving the surface of the aluminum alloy plate. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical technology. According to the difference between the content of aluminum and the added elements in aluminum alloys, aluminum alloys are divided into 1 series aluminum alloys, 2 series aluminum alloys, 3 series aluminum alloys, 4 series aluminum alloys, 5 series aluminum alloys, 6 series aluminum alloys, and 7 series aluminum alloys. Alloys, 8-series aluminum alloys and 9-series aluminum alloys, among which 1-series aluminum alloys belong to the series with the largest aluminum con...
